Your customer rejected your latest shipment due to color. You checked the color before you sent it and it passed tolerance… You did everything the same way last time and it passed tolerance… So why did it get rejected now? We get this question from our customers all the time. The Dreaded “Error Stack” Color rejections create waste and increase production costs. Unfortunately, there are a lot of variables that contribute to the color you produce,...
For the last few Decembers, we’ve provided you with a list of “top color measurement blogs” for that respective year. As we reviewed this year’s list, we noticed that your favorite/ the most-read blogs could be categorized into a few buckets. So, without further ado, here’s 2018’s top blog topics! 2018’s Most Popular Color Measurement Topic: Tolerancing Not to our team’s surprise, Tolerancing – what it is/what it means for your busines...
Each year, Pantone announces its highly anticipated “Color of the Year”. The selection is intended to serve as a strategic direction for design and color-conscious industries as well as a conversation piece around our culture, where it is going and what we collectively need…and it certainly gets everyone talking about color! Color is no longer just something we see and appreciate - it enhances and influences the way we experience life. Color, as a strategic element of d...
Like geographic coordinates – longitude, latitude, and altitude – L*a*b* color values give us a way to locate and communicate colors. What’s the history of L*a*b*? In the 1940’s, Richard Hunter introduced a tri-stimulus model, Lab, which is scaled to achieve near uniform spacing of perceived color differences. While Hunter’s Lab was adopted as the de facto model for plotting absolute color coordinates and differences between colors, it was never formally accepted as...
To understand how color management works, you need a basic knowledge of the additive and subtractive systems of color reproduction. Both use a small number of primary colors that combine to produce a large number – or gamut – of colors… but the way they do that is quite different. In our Color Perception Part 1: The Effect of Light post, we explained how the visible color spectrum (we know it as the rainbow) encompasses light wavelengths from approximately 380 to 720 nm. By breaking the visible...
If you work in the print and packaging industry, standards can help you set clear expectations for clients, solve problems in your workflow, and improve productivity. They can also bring an independent perspective to production. Printers aren’t the only ones who should keep up with standards. Brands who are concerned with quality, price, and speed to market can also benefit because it allows them to compare print providers and choose the best candidate. The ISO and other standards organiz...
When customers are just getting started with color management, they often ask, "What is the difference between a spectrometer and a spectrophotometer?". With such a minute spelling difference, it's easy to make a quick typo and get the wrong answer for this color question. So...what's the difference? Spectrometers vs. Spectrophotometers What is a Spectrophotometer? A spectrophotometer is a color measurement device that is used to capture and evaluate color on just about anything, in...
Surface appearance can change your perception of color. Think of a glossy magazine. If the light is shining directly on the page, you may need to tilt the magazine and change the reflection angle to clearly see the colors. Likewise, a textured surface may appear to be a different color than a smooth surface of the same object. Since spectrophotometers determine a color’s spectral values by shining light onto the surface and measuring the reflectance, choosing the right instrument and the...
At the end of each year we enjoy looking back at our most popular blogs because it’s a great way for us to understand what interests you – our readers. As the years go by, we have discovered a few make the list again and again. This year the Top Ten is split down the middle between color theory and manufacturing best practices. Have you read them all? Top Five Color Theory Topics of 2017 1. Color Perception Part 1: The Effect of Light Remember “The Dress?” Was it ...
In the sign and display graphics business, as in many other segments of the printing industry, shorter runs and reduced cycle times can stress even the most efficient wide format printing operations. By implementing a color-managed RIP-to-roll (or RIP-to-rigid media) workflow, these operations can ensure that color is right the first time and every time to help speed work through the shop and meet color expectations.
